After Team 7 successfully finds Tora, the lost cat of the Fire Daimyō's wife, they return it back to her. With their mission successfully completed, the Third Hokage informs them of the available D-rank missions, such as babysitting the chief counsellor's three year old.
"no no no!" Naruto shouted "i want a real mission with excitement and challenges"
"This is stuff that even academy students can do" Aika agreed with her brother and Naruto put his arm around his sister grinning like an idiot happy that she agreed with him.
Iruka lectures them "like every beginner genin with no experience, you must start with simpler missions to develop your skills."
The Third goes on to explain that "with a higher ranked mission comes higher difficulty and greater risk to the shinobi."
"we're ninja now and we want to be treated as ninja" Naruto argued
Amused at his statement, the Third decides to give the team a C-rank mission to escort Tazuna, a master bridge builder, to the Land of Waves. When Tazuna meets the team, he expresses disbelief in the fact that kids are going to be guarding him.
"Pink hair, arrogant, kid the stupid look on his face, and a little princess" Tazuna said
"...princess?" Aika questioned as Kakashi held Naruto back from attacking Tazuna.
"um escuse me" Aika said walking up to Tazuna
"what is it princess" he said
"I might look like an adorable princess and i thank you for that compliment, but you are relying on this princess to get you safely to your town, basically your life is in my hands so be careful and lets get you safely back without any little accidents" Aika said in a threatening tone, Tazuna looked a bit scared as did Kakashi
"Aika we can't hurt the client" Kakashi said
"Of course not sensei I won't, but their might be enemies" Aika said sweetly
Sasuke looked at her and thought so meaning she would perpously let any enemy get close to Tazuna enough to scare him or hurt him... you know i'm kinda impressed with her
They head back to their homes to pack up then they start making their way to the Land of Waves, two chūnin-level Kiri-nin emerge from a puddle and binds Kakashi with shuriken-laced chains, before pulling and ripping him apart. With Kakashi "defeated", the duo turn their attention to Naruto, who freezes up. Before they can land an attack, Sasuke intervenes and saves Naruto.
The duo split up, leaving one behind as the other charges at Tazuna. Sakura steps in front of Tazuna to defend him, before Sasuke appears in front of her to aid. Aika threw kunai that got stuck between their chains locking the two ninja together. Then Kakashi appears and effortlessly defeats the duo, though Naruto does attain a small scratch from one of their Metal Gauntlets, which contained poison.
It is revealed that Kakashi used the Substitute Technique to escape the duo's initial attack, suspecting an ambush when he discovered their puddle on a clear day. Kakashi compliments Sasuke and Aika for their courage, but expresses disappointment in Naruto and Sakura with how poorly they handled the situation. Tazuna questions why Kakashi took so long to help, with the latter explaining that he could have defeated them quickly but needed to know who their target was.
Kakashi points out that their target was Tazuna and that had he told them that he would be hunted by ninja, the mission would be a B-rank or higher, and a different team would have been assigned. Sakura suggest they quit the mission, not only due to the higher difficulty, but because of Naruto's wound. Unwilling to jeopardise the mission, Naruto decides to take out a kunai and uses it to remove the poison from his hand.
He then makes an oath that he will never run away or back down from any mission, threat, or enemy, as well as not lose to Sasuke. After this, Kakashi bandages Naruto's wound so he doesn't bleed out, but discovers that it had already begun to heal due to the Nine-Tailed Demon Fox. Kakashi looked over to Aika to see a bit of red in her eyes, it's been like that since the Hokage's office.
Elsewhere, Gatō, the man who hired the Demon Brothers to eliminate Tazuna, complains about their failure to Zabuza, the duo's apparent boss. Zabuza raises his Kubikiribōchō at Gatō to shut him up, and states that he will handle it himself. Gatō informs him that they will be expecting another assault and that a high-level ninja is accompanying Tazuna. This doesn't faze Zabuza, who just replies that he is the "Demon of the Hidden Mist".
